Abstract
Two water mites species of Torrenticolidae are reported from China. Testudacarus sinensis Gu and Guo sp. nov. is described as the second species of Testudacarinae in Chinese fauna and the 22<sup>nd</sup> species of the subfamily. Moreover, the first record from China is given for Torrenticola rangareddyi Pešić and Smit, 2019. In addition to an updated key for all species of Torrenticolidae recorded from China, the dorsal plate arrangements of torrenticolid mites are reviewed to provide further references and data for the taxonomy of Chinese Torrenticolidae.
